No problem. Thank you for the update.

Ok - That looks like it worked. I guess I was expecting a file named 802_15_4_lib_iar.a that had built to be compatible with IAR 8. Sorry for the confusion.

Thanks Vidar

Hello,

Sorry, but I'm not sure I understand the question then. The compatible alternative is "\nRF5_SDK_15.3.0_59ac345_new\components\802_15_4\raw\802_15_4_lib_gcc.a"

Hello Vidar -

Yes - I saw this post that you reference here. This is why I asked my question. My question is still valid. Specifically - the statement that you provide:

- If the project contains one of the precompiled libraries listed below, replace it with the IAR 8 compatible alternative
(there are no projects targeting nRF51 in this SDK).

Where can I find the 'IAR 8 compatible alternative' that is referenced?

Hello,

You may use the _gcc variant of the library in IAR 8. Excerpt from the SDK release notes:

Note for IAR 8 users:
(Libraries for IAR 8 require wchar_t to be of size 32 bits while IAR 7 requires 16 bits).

To run a project using IAR 8, follow these intructions:
- Open the IAR project in IAR 8. The IAR workbench will automatically generate an IAR 8 compatible project file.
- If the project contains one of the precompiled libraries listed below, replace it with the IAR 8 compatible alternative
(there are no projects targeting nRF51 in this SDK).
- Save the project.
- When building the project, you might get the warning: "The header file 'cmsis_iar.h' is obsolete and should not be used. [...]".
- The problem is described in DevZone post: devzone.nordicsemi.com/.../iar-ewarm-8-22-1-complains-about-cmsis_iar-h
The solution is to remove all occurrences of #include <cmsis_iar.h>.

The affected libraries are:
- micro-ecc crypto:
- IAR7: Includes library located in the folder named “…_iar\…”.
- IAR8: Switch to using the library from the folder named “…_armgcc\…”.
- nrf_cc310, nrf_cc310_bl, and nrf_oberon:
- IAR7: Link to a library where “short_wchar” is part of the folder name.
- IAR8: Link to a library without “short_wchar” in part of the folder name.
- Gazell, NFC Tag, and 802.15.4:
- IAR7: Includes the library where the file name ends with “_iar”.
- IAR8: Switch to using the library with similar file name that ends with “_gcc”.
